Description:
Updated patch package fixes security vulnerabilities:

* In GNU patch through 2.7.6, the following of symlinks is mishandled
  in certain cases other than input files. (CVE-2019-13636).

* A vulnerability was found in GNU patch through 2.7.6 is vulnerable to
  OS shell command injection that can be exploited by opening a crafted
  patch file that contains an ed style diff payload with shell
  metacharacters (CVE-2019-13638).

* A vulnerability was found in do_ed_script in pch.c in GNU patch through
  2.7.6 does not block strings beginning with a ! character. NOTE: this
 is the same commit as for CVE-2019-13638, but the ! syntax is specific to
  ed, and is unrelated to a shell metacharacter (CVE-2018-20969).
